Hey,

What are the standard air screw settings for a 93 RS?

I have in my head it is 1 and 1/2 turns out.

My chart doesn't have the 93 specs but the 91 n 92 R / RS both have

Upper carb aka left side 2 turns out

Lower carb aka right side 1 and a half turn.

Here's a tip most people don't know about. When you turn the air screw all the way in tight. The first quarter of the turn doesn't count.

You should start your turns count when the screw slot is at 12 o'clock position.

Cheers for that.

Did not know about the first 1/4 turn.

Just did a full rebuild on the carbs. So good to know.
